Aftermarket CPU Heatsink results.

Well obtused.

cool and relevant

Eh, 5 minutes of OCCT/LinX/IBT/Prime95 isn't enough. Every new system I build gets subjected to 12 hours of Prime95 and 50 successful passes of LinX.

On Intel i7 920/930 chips with high end air coolers (Thermalright), that ends up sitting around 70-80C. Good enough to be used as a space heater for a room, or to warm up a egg nicely! hahaha

When I first built the system in april or so (I made another thread there) I did a prime burnin overnight to make sure it was stable. This time around I just did a quickie because I've never taken any before/after results lol.

What was the point of that, you're just wasting watts and generating excess heat when idle.

cn'q has caused some issues in the past with overclocking- not properly adjusting the multiplier back. Ill turn it on this time around and see if all is well.

I havent built a pc in years. I am still on an opteron 165/DFI mobo. With 2 gigs of ram and a radeon hd4500's or something hah. Maybe I'll build a new one for BF3

One thing no one mentioned is optimizing the heatsink to cpu interface.
You need to polish the heatsink until it's like a mirror to get the best heat transfer. Go thru 400, 600, and 1000 grit wetndry paper on a glass plate then use rubbing compound and buff it up. Then apply a really good silver compound and mount it.
You will get better results than using the heatsink out of the box.
HTH..

Aight, just tested with Prime95 and getting 54-55 degrees with stock heatsink and 100% load

If you're going to do that you need to lap both the CPU and the heatsink so that they are perfectly flat. Once this is done you do not need any thermal interface material since there will be no microscopic gaps between the CPU and heatsink. In most cases this is not really worth the trouble.

why polish when thermal gel does all the work of transfering the heat???

You must have one of the rare good units. I've read a lot about them failing in a matter of weeks due to weak pumps.

I guess so, I think its one of the original blue ones. When I first got it the pump was completely silent, it does make some noise now, 6 years later, but the rest of the computer is still louder, which is pretty darn quiet.
